TROUBLE SHOOTING
SPIDER AND INSECT WARNING!!!
Spiders and small insects occasionally
spin webs or make nests in the grill burner
tubes during transit and warehousing.
These webs can lead to gas flow
obstruction which could result in a fire in
and around burner tubes. This type of fire
is known as “FLASH-BACK” and can
cause serious damage to your grill and
create an unsafe operating condition for
the user.
Although an obstructed burner tube is not
the only cause of “FLASH-BACK”, it is the
most common cause.
To reduce the chance of “FLASH-BACK”,
you must clean the burner tubes before
assembling your grill, and at least once a
month in late summer or early fall when
spiders are most active. Also perform this
burner tube cleaning procedure if your grill
has not been used for an extended period
of time.
WHEN TO LOOK FOR SPIDERS
You should inspect the burners at least
once a year or immediately after any of the
following conditions occur:
1. The smell of gas in conjunction with the
burner flames appearing yellow.
2. The grill does not reach temperature.
3. The grill heats unevenly.
4. The burners make popping noises.
BEFORE CALLING FOR SERVICE
If the grill does not function properly, use
the following check list before contacting
your dealer for service. You may save the
cost of a service call.
